SHlFTlNG MECHANISM FOR GRAIN-BINDER TABLES.

SPECIFICATION forming part of Letters Patent No. 372,515, dated November 1, 1887.

Serial No. 189,556. (No model.)

To all whom it may concern:

Be it known that I, JOsEPI-I P. BULLOCK, of Milwaukee, in the county of Milwaukee,and in the State of \Visconsin, have invented certain new and useful Improvements in Shifting Mechanisms for GrainBinder Tables; and Ido hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to shifting mechanisms for grain-binders, and will be fully described hereinafter.

In the drawings, Figure 1 is a side elevation of a portion of a grain-binder with my invention in place thereon. Fig. 2 is a rear elevation of the same, looking up from lineocx, Fig.

1. Fig. 3 is a detail.

Aisthe binderframe, to the beam B of which is secured two or more brackets, O, that are slotted at their outer ends to form jaws,between which rest the lower ends of rocking supports D for the rear of the binder-table.

The main portion of each rocking supportD is composed of a single strip or wire bent toform a loop, through which and thejaws ot'thc adjacent bracket pass securing pins a, and the ends of said strip or wire are titted in sockets depending from a grooved segmental rest, I), for the "gas-pipe c of the hinder-frame. From each of the rests b a hook, (1, projects up into an opening in the gas-pipe and serves as a stop to limit the play of the supports. A gas-pipe also extends across the inner and u pper edge of the biudenlraine and under the table, and this pipe rests upon two or more brackets, E, that are secured to the frame-work of the machine. A bell-crank lever, F, is also pivoted to the framework, and one end is connected with the gas-pipe D by a link,f, and pinf, whileits other end or arm is connected to an elbow hand-lever, G, by a link, g, and by means of these lastnamed connections the binder-table is adjusted to suit the length of grain being harvested, and the table is locked in adjustment by a pawl, h, and segment 71/.

It will be seen that the lower ends of the supports D rest directly upon the brackets 0,

and that there is only the slightest possible strain on the pins a, while there is very slight frictional contact between the parts and no liability to get out of order. At the same time it will be noticed that the ends of the bent strips or wires forming the supports are equidistant from a common center, and therefore a double support is provided, whereby the strain on the pins to is further lessened.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a grain-binder, the combination of the binder-table, hand-lever, and operative connections, with upper stationary supports and lower rocking supports, the latter being severally composed of a single strip or wire bent to form a loop, and a segmental rest secured to the ends of said wire, as set forth.

2. In a grain-binder, the combination of the binder table, hand-lever, and operative connect ions, with upper stationary supports, lower rocking supports severally composed ofa single strip or wire bent-to form a loop, and a seg 7c mental rest provided with depending sockets to engage the ends of said strip or wire, as set forth.

3. In a grainbinder, the combination of the binder table, hand-lever, and operative con 'nections, with upper stationary supports,

JOSEPH P. BULLOCK.
